' AUTOAND SCREEN" DOOR LATCH.

Specification of Letters Patent.

Application'fl led'December19, 1916. Serial no. 137,749.

To all whom it may concern:

Be it known that I, GEORGE E HrroH- COCK, a citizen of the United States, residing at Flint, in the county of Genesee and State of Michigan, have invented certain Screen Door Latches, of which the following is a specification. Y

My invention relates to an improvement in auto and screen-door latches, and .the object is to provide a simple form of latch applicable to these and other types of doors, of few and reversible parts, simple in construction, easily operated," and not likely to get out of order, and which latch will be effectual in the performance of the functions ascribed to it.

The invention consists in a slidable latch, a lever of peculiar construction slidably connected with the latch, a push for operating the lever to positively move the latch in and out, as well as in other features of construction, which will be more specifically described in the further exposition of the invention.

In the accompanying drawings Figure 1 is a view of the latch wit-h the face-plate removed;

Fig. 2 is a side view of the push;

Fig. 3 is a similar view of the slide latch;

A, is the latch-case, and 1, the removable face-plate, the two being preferably mortised together by suitable lugs and slots and a removable screw 2, or their equivalents.

The numeral 3 is the slide-latch, which operates through a slot 4 in the edge. This slide-latch has an elongated slot 5, through which it receives the stud 6 permanently fixed within the latch-case, and which forms a guide-stop for the slide-latch. The slidelatch is reversible by simply removing it and turning it over, so that the latch can be used on either right or left doors.

The slide-latch is controlled by a lever 6 fulcrumed at or near its center on a pivot 7 This lever is curved, as shown, at the free or operative end, and slides through a notch 8 in the slide-latch.

A slidable plunger 9 extends out through the top of the case, and is pivotally connected at its inner end with one end of the lever 6 its outer end having a button 10 thereon, and'its inner end flanged to form a recess for one end of the spring 11, which extends therefrom over the pivot 7, and

thence to a pin 12, for returning the latch and the various parts at thispoint to their normal position.

The latch could be controlled without the spring, as the plunger, lever and latch are so organized, combined and connected that the positive movement of lar movement to the others. The spring, however, throws the parts back to their normal operative position, which would otherwise require to accomplish this en Patented May 14, 1918. v

one imparts a simi-.

a lifting of the plunger A locking-slide 13 may be provided to enter the notch 14 in the plungerto hold the parts in their inner or withdrawn position, when it is desired that the latch should be inoperative.

, Besides the slide latch being reversible,

it is evident that both-the push and the lever may also be reversed to adapt them to the reversal of any other parts, but not" necessarily.

It is obvious that, while the various elements described are more or less essential in the form shown, they are, nevertheless, subject to more or less variation; and it is not my desire, therefore, ited to what I have shown and described, they only being a form of the invention.

0 aim:

1. A door-latch comprising a case, a reversible slide-latch slidably mounted within the case, said latch provided with recesses in either side thereof, a pivotally mounted lever arranged below and substantially parto be strictly lim-.

allel with the slide-latch, the outer end;

thereof being. bent in the form and adapted to be received within one of the recesses within the slide-latch, said lever being pivoted centrally of its body portion in such a manner as to causethe cam to move inwardly and upwardly through the recesses, and a vertically arranged actuated plunger pivotally connected to the outer free end of said lever whereby the cam is caused to impart a horizontal movement to said slide-latch when actuated.

2. A door-latch comprising a case, a reversible slide-latch, slidably mounted within the case, said latch provided with recesses in either side thereof, a pivotally mounted of a cam lever arranged below and substantially parthe recesses within the slide-latch, said lever being Eivoted centrally of its body portion in sue a manner as to cause the cam to move inwardly and upwardly through the recesses, a vertically arranged actuated plunger pivotally connected to the outer free end of said lever whereby the cam is caused to impart a horizontal movement to said slide-latch when actuated, a spring arranged beneath the plunger whereby the plunger and latch are held in an outward position, and a lock adapted to engage a notch in the side of the plunger whereby the plunger and latch may be held in a close position against the tension of the said spring.

In testlmony whereof I aflix mymsignature.

GEORGE HITCHCOCK.
